For more than 60 years, Shafer actuators have been recognized for their reliable performance in pipeline service. The SH-Series helical spline gas-over-oil actuator continues the tradition. The double-acting hydraulic model is perfect for a variety of small valve (2"to 8") pipeline applications including:

• Transmission
• Meter runs
• Blowdown Valves
• Compressor Stations
• Storage
• LDC’s
• Gathering
• Gas Plants

• No power gas regulators and relief valves required
• Zero Leakage Piston
• Typical Size range: Small Valves from 2" to 8"
• Straight Line Torque Range: From 2,250 in-lbs to 18,000 in-lbs
• Typical Pressure Ranges: From 400 psig to 1,500 psig
• Temperature Range: -20°F to +120°F
• Small Envelope
• No Valve Stem Side Loading
• 50 Year Design Life Backed by 10 Year Shafer Guarantee
• Traditional Shafer High Pressure Controls with Manual Override
• Precise Speed Control – No Torsional Impact
• No Internal Corrosion Problems
• Gas Hydraulic Tanks prevent gas contaminants from entering the actuator
• Vastly Extended Seal Life
